Laser Bracket USB Port
From MobileRobots Research and Academic Customer Support
What is the USB port on the back of the black SICK LMS-200 laser mounting bracket on my Pioneer for?
This port is connected to the onboard computer's USB interface. Its primary purpose is for use with a USB joystick, which will allow you to drive the robot when a program is running such as ARIA's 'demo', 'sickLogger', ARNL's 'guiServer', 'arnlServer', 'sonarnlServer', or 'mogsServer', or any other program which includes joystick driving.
It is not connected to the SICK LMS-200 laser.
